Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
7. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
8. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
11. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

FAQ

Can I use the HLG-120H-C1050B with a building automation system to dim LED fixtures?

Yes. The HLG-120H-C1050B has a 1-10V/PWM dimming input, making it compatible with building management systems that output standard dimming signals. It delivers 1050mA constant current at up to 155.4W, suitable for automating light levels in commercial spaces based on occupancy or daylight schedules.

Is the HLG-120H-C1050B suitable for dimmable LED track lighting in a gallery or showroom?

Yes, provided the track light modules operate at 1050mA with a combined forward voltage between 74V and 148V. The dimming input allows precise brightness control for accent lighting, which is essential in galleries where light levels affect artwork display. The constant current output ensures uniform brightness across all modules.

Can the HLG-120H-C1050B power LED arrays in outdoor architectural lighting with dimming?

Yes. With the series' IP65/IP67 rating and a case temperature (Tcase) range of -40°C to +90°C, the HLG-120H-C1050B can drive outdoor architectural LED fixtures while providing dimming control. It handles 155.4W at 1050mA constant current, suitable for facade lighting, wall washers, or landscape uplights that require brightness adjustment.

What is the CC voltage range of the HLG-120H-C1050B and why does it matter?

The CC voltage range is 74-148V. This means the driver automatically adjusts its output voltage within this window to maintain a steady 1050mA through the LED load. If your LED string's forward voltage falls outside this range, the driver cannot regulate properly. Always ensure your total LED forward voltage sits between 74V and 148V.

How does the HLG-120H-C1050B differ from the C1050A and C1050AB versions?

All three deliver 155.4W at 1050mA with a 74-148V CC range. The C1050B (this model) includes a 3-in-1 dimming input (1-10V, PWM or resistance) but no output adjustment potentiometer. The C1050A has the adjustable potentiometer but no dimming input. The C1050AB combines both adjustment and dimming in one unit.

Can the HLG-120H-C1050B be mounted in a damp indoor environment like a swimming pool area?

The series is rated IP65 or IP67, protecting against dust and water jets, which is generally adequate for damp indoor environments such as pool halls where splashing may occur. Working humidity is rated 10-95% RH non-condensing, so it should be mounted where condensation cannot form and away from direct spray from pool fixtures.
